Safety precautions
When not in use, machines must be stored in a dry,
high place or locked away out of reach of children.
j)
Always disconnect the machine from the electric sup-
ply when it is not in use (e.g. during breaks between
working), before making adjustments, before carrying
out care and maintenance and before changing saw
blades. This safety precaution prevents the machine
starting unintentionally.
k)
Remove any adjusting key or wrench before switch-
ing the machine on. A wrench or a key left attached to
a rotating part of the machine may cause personal injury.
l)
Before use, the machine, the saw blade and acces-
sories must be checked carefully to ensure that all items
function faultlessly and as intended. Check that mov-
ing parts function correctly without sticking and that
no parts are damaged. All parts must be fitted correctly
and fulfill all conditions necessary for correct opera-
tion of the machine. Damaged parts must be repaired
or replaced properly by an authorized service center.
m)
Avoid skin contact with drilling slurry.
n)
Wear a protective mask during work that generates
dust. Cutting materials hazardous to the health (e.g.
asbestos) is not permissible.
o)
Follow the instructions concerning care and main-
tenance.
Electrical safety
a)
Take steps to avoid the risk of electric shock. Avoid
body contact with earthed or grounded surfaces such
as pipes, radiators, ranges and refrigerators.
b)
Check the machine’s supply cord at regular intervals
and have it replaced by a qualified specialist if found to
be damaged. Check extension cords at regular inter-
vals and replace them if found to be damaged.
c)
Check the condition of the machine and its acces-
sories. Do not operate the machine and its accessories
if damage is found, if the machine is incomplete or if
its controls cannot be operated faultlessly.
d)
Do not touch an electric cable that has been dam-
aged while working. Switch off at the main switch and
unplug the cable at the power outlet.
5.4
e)
Damaged or faulty switches must be replaced at a
Hilti service center. Do not use the machine if it cannot
be switched on and off correctly.
f)
Have the machine repaired only by a trained electri-
cal specialist (Hilti service center) using genuine Hilti
spare parts. Failure to observe this point may result in
risk of accident to the user.
g)
Do not use the supply cord for purposes for which
it is not intended. Never carry the machine by the sup-
ply cord. Never pull the plug out of the power outlet by
pulling the supply cord.
h)
Do not expose supply cords to heat, oil or sharp
edges.
i)
Connect the machine and its ancillary equipment only
to a power source equipped with an earth/ground con-
ductor and ground fault circuit breaker (PRCD). Check
that these items are in perfect working order before
operating the equipment. Install an earth/ground rod
if a generator is used or if no earth/ground conductor
is present in the on-site electric supply. Operation of
the machine without an earth/ground connection is not
permissible under any circumstances. With no
earth/ground connection, faulty insulation on a part of
the machine or inadvertently sawing into a live cable
presents a risk of fatal accident.
j)
Make sure that the mains voltage corresponds to the
specification given on the type plate.
k)
Electric cables and their plug connectors must be
kept dry. When not in use, close power outlets with the
cover provided.
l)
Use only extension cables which have an adequate
conductor cross-section and are approved for the intend-
ed field of use. Do not work with extension cables when
they are rolled up. This can result in a drop in output
at the equipment and may cause the cable to overheat.
m)
Disconnect the power cable before beginning clean-
ing and maintenance work or in the event of a lengthy
interruption between periods of operation.
n)
Please note that certain components of the power
converter retain an extremely dangerous (potentially
fatal) high voltage for up to 10 minutes after discon-
nection from the electric supply.
